摘要:
The invention herein refers to a hot, cold or warm forging process comprising conforming a disk (15, 20) through forging to obtain a pre-formed part (16,21 ), the forging process creating at least one recess (162,212,213) on the pre-formed part, the recess having a bottom area; removing a section (17b,22b) of the bottom area; and conforming through forging the pre-formed part (16,21) to obtain a final hollow part (18,23). The process enables the obtainment of a final part - a ring with an outer flange, for example, a bushing or an inner ring of an angular contact bearing - with substantial reduction on the mass of the wasted material. A punch was also created for this purpose.
摘要(中):
本发明是指热,冷或热的锻造工艺,其包括通过锻造使盘(15,20)形成,以获得预成型部分(16,21),所述锻造工艺在其上形成至少一个凹部(162,212,213) 预成型部分,凹部具有底部区域; 去除底部区域的部分(17b,22b); 并通过锻造预形成部分(16,21)以获得最终中空部分(18,23)。 该过程使得能够获得最终部件 - 具有外部凸缘的环,例如角接触轴承的衬套或内圈,并且大大减少了浪费的材料的质量。 为此目的也创造了一个冲击。
